Yes, but you need to set up the CTM to draw the layers in the right place. To be clear, you're asking the views' layers to -renderInContext:, not the views themselves. We use -renderInContext: to draw entire layer trees into one big context. You obviously aren't doing the same thing, but the principle is identical. You might want to look into our CALayer extension method for doing so: https://github.com/omnigroup/OmniGroup/blob/master/Frameworks/OmniQuartz/CALayer-OQExtensions.m#L497 --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
